Rep. Mike Honda, facing a 2014 challenge from a well-funded fellow Democrat, is willing to sing for his supper – or, at least, to help fill his campaign coffers.

“Congressman Mike Honda is a master on the karaoke mic. Everyone from DC to California’s 17th Congressional District knows it. SF does too,” reads an invitation to the next fundraising event for Honda, D-San Jose. “Let’s celebrate Mike’s re-election effort by joining together for some fun, drink, and embarrassment on Friday, August 16th at Pandora Karaoke Bar in San Francisco! (If you don’t sing, don’t worry – come anyway!)”

The host committee includes former Assemblywoman Fiona Ma, D-San Francisco; San Francisco Democratic Party executive director Ally Medina; and several others. Tickets for this “On the Mic with Mike” event cost from $45 to $1,000, but there’s no mention of how much you can pay to avoid listening to these folks sing.

Meanwhile, challenger Ro Khanna will be busy Friday night holding his umpteenth meet-and-greet at a private home in Cupertino; on Saturday, his campaign will be going door-to-door in Fremont, Milpitas, Cupertino and Sunnyvale.

Khanna is coming off a high-exposure week that started with his appearance on Current TV’s “The War Room:”

California Lt. Gov. Gavin Newsom starting next month will host a new weekly series on Current TV, the liberal news-and-policy channel cofounded and chaired by former Vice President Al Gore.

“The Gavin Newsom Show,” with hour-long episodes, “will have a decidedly California touch as Newsom interviews notables from Silicon Valley, Hollywood and beyond,” according to Current’s news release, and will be executive produced by Mia Haugen, a former executive at The Street, Forbes and CNN.

“Gavin Newsom is a courageous leader who has boldly seized every opportunity to create positive social change,” Gore said in the news release. “First as a successful entrepreneur, then in his role as mayor of San Francisco, and now as lieutenant governor, Newsom touches many worlds – business, politics, entertainment and activism. We are honored that Current TV will be bringing his curiosity, intelligence, insights and enthusiasm to television.”

Asked whether doing the show will in any way detract from the time and energy Newsom gives his official duties as lieutenant governor, spokesman Francisco Castillo replied, “Absolutely not.”

“The show will be taped once a week,” Castillo said. “The time and energy he gives to this show is no different than what he did for his weekly radio show as mayor — except now with a broader audience. It’s about showcasing California, which would only benefit the state.”
